Hi All. I am new to OPNsense. Currently evaluating it for my requirements. So far very happy with what I have seen. Kudos to all those from the ground up who are involved in this project!

I am going through basic security tuning of my OPNsense 18.1.6 install. I have added a user with basic rights through the WebGUI. I have now used the console via root to add the user to the wheel group in /etc/group.I have attempted this by direct editing the file and by using the "pw usermod" command.

I am able to SSH in using this basic user without issue. I was able to su to root once successfully, however no more. OPNsense / FreeBSD overwrites the /etc/group file every time I change it!

How does anyone else su to root with this behaviour? Is there a fix for this?
